Final answer:
To forecast the return on investment with new suppliers having better delivery track records, a decision support system is the right choice. It specializes in analyzing various scenarios to predict future performance.
Step-by-step explanation:
To forecast the return on investment when using new suppliers with better delivery track records, you would use a decision support system (DSS). DSS can assist in modeling, analyzing, and visualizing different scenarios to help predict future performance under varying conditions. Unlike a management information system or a transaction processing system which largely deal with routine data processing, a DSS provides the advanced analytics and simulation capabilities needed for financial forecasting. It's not primarily focused on handling customer relationships or day-to-day transactions but rather on supporting complex decision-making processes with a predictive component.
